Place the pretzels in a large resealable ziplock bag.
Mix together seasonings with the sriracha, oil, and butter and pour over the pretzels. Shake the bag to coat all the pretzels.
Turn the oven to 250 degrees. Let the pretzels marinate until the oven comes to temperature.
Spread the pretzels out evenly on a parchment lined sheet pan. Bake at 250 degrees for 45-50 minutes, stirring halfway through the baking time. When you go to stir the pretzels, open the oven door and let the sriracha fumes escape before you stir the pretzels. You'll know the pretzels are done when they look well dried and slightly darker.
Let the pretzels cool completely before serving. Store in an airtight container.
